Merge branch 'pb/blame-funcname-range-userdiff'
"git blame -L :funcname -- path" did not work well for a path for which a userdiff driver is defined. * pb/blame-funcname-range-userdiff: blame: simplify 'setup_blame_bloom_data' interface blame: simplify 'setup_scoreboard' interface blame: enable funcname blaming with userdiff driver line-log: mention both modes in 'blame' and 'log' short help doc: add more pointers to gitattributes(5) for userdiff blame-options.txt: also mention 'funcname' in '-L' description doc: line-range: improve formatting doc: log, gitk: move '-L' description to 'line-range-options.txt'
